'Ib (IZZ whom it may concern: I

known that We WILLIAM A. Bunsen I a i .tlENRY WV. MEIER, citizens of the United 211 iii States, residing at Long Grove, county of Scott, and State of Iowa, have invented certain new and useful. Improvements in Rail l lates and. Clamps, of which the following is a specification.

This invention relates to rail plates and clamps.

The present invention has for its object the provision .of a rail plate and clamp having novel projections adapted to be driven into the tie to prevent displacement thereof when spiked, and, further, anew brace for the rail which, together with the plate, are formed in. an improved manner to interlock with each other and with the rail, insuring the retention of the latter on the tie without displacement either on a straight track or on a curve where the lateral pressure is very great.

The present plate and clamp prevent cut-.

ting ofthe tie by the rail and thus prevent loosening of the spikes.

If the invention is used on a concrete or a concrete and metal tie, it can be secured by bolts instead of spikes.

The invention is fully set forth hereinafter and the novel features are recited in the appended claims.

In the accompanying drawings :-Figure 1 is a vertical section. showing the clamp plate in use; Fig. 2, a side elevation of the abutment; Fig. 3, a view of the inner face thereof Fig. 4, a view of the outer face thereof; Fig. 5, a top perspective of the plate; Fig. 6, a bottom perspective thereof; Fig. 7, a top perspective of a modified plate; and Fig. 8, a bottom perspective thereof.

Referring first to Figs. 5 and 6, the rail plate 1 is provided on its under surface with longitudinally extending edged ribs 2 having abrupt shoulders at their ends and preferably constructed and arranged as shown, the outermost ones extending for a relatively great distance and the innermost ones being shorter and separated. by a considerable space at their inner ends, thus increasing the number of shoulders on the ribs which engage with the wooden tie 3 and increasing the tendency of the plate to resist longitudinal displacement due to lateral pressureof the Wheels of the cars, it being understood that the ribs are embedded in the tie when the plate is seated thereon- The upper face of the plate has a seat or chair at. fortlie rail 5,said seat being just 'wide enough-to receive the base of the rail, the innermost part of the plate bein pro-- vided with ears or lugs 6-which are a apted to overhan' the base flange of the rail, as at 7. The 0t er margin of the seat 4 is de* fined by a straight shoulder 8 extending entirely across the plate 1 and of a depth substantially that of the height of the outer edge 9.01, the base flange of the rail. The" solid abutment or'brace 15 which preferably engages the rail underneath the head and at the juncture of the web and base thereof, rounded parts 16 and 17 being provided for that purpose, the lower face 18 of the brace conforming to the top of the base of the rail, and the brace may be. widened toward its outer face, as shown at 19,.if desired, the angle 20 of the outer face being that best suited to give great strength to the brace. The lower part of the brace is rovided with a flat base 21 of a width su cient to fit snugly, yet easily, on the surface 12-between the flanges 13 so that the brace is prevented from twisting on its said seat. The base 21 is continued in under-projecting disposition at 22, preferably of some greater width than the base 21 and underlies the end of the plate 1, said part 22 being disposed flat against the raised surface 11 and of such thickness that'it will fill the space between said surface and the top of lthe tie. Extending through the parts 21 and 22 of the base are spike holes 23 for the recep- 100 there are provided raised lugs 26 to abut- I againsttheedge of the base of the rail atthat point; The entire under surface of the plate is in the same plane and there are provided the ribs 2, as before,but said ribs start'from the Outer ends of the plate.

Having thus'described our invention, what we 'claimas new and desire to secure by Letter's Patent, is

.. 1. Ina rail plate and clamp, t-hli combi nation with a rail plate having a seat for therail and at one end being ofiset or raised,

, *Qof a brace or abutment for the rail which is fprovided with spaced connect-ed bases receivi'ngth'e raised or ofi'set part of the plate.

2. In a rail 'plate'land clamp th e combination'with .a rail plate having a seat for the rail and at oneend being offset or raised, {of a brace or abutment for the rail which is Tao,

provided with spaced connected bases receiving the raised or offset part of the plate, said brace and raised or ofiset part of the plate beingprovi'ded with jinterlocking devices to preventtwi'sting of the abutment.

3. In a rail plate and clamp, the combi I the rail and at one end belng ofiset or ra sed,

nationwith a rail plate'having a seat for of -a'. brace pr abutment for the rail which is provided with spacedconnected bases receifving theraised or ofifset part of the plate,

onats upper surface w1th a seat m which 1s said ofiset part of the plate being provided ment.

received the upper base 1.- In a rail plate and clamp, the combination with a plate provided with a rail seat having at one side a shoulder to engage the edge of the rail base and at that end being provided with a raised or oflset' art whose upper surface is provided with anges, the

' plate, the double base of the brace and the.

plate being'provided with openings for the reception of fastenings, and the other end of the plate being provided with openings for therecept-ion of fastenings.

In testimony whereof, we hereunto afiix our signatures in presence of two witnesses.
